FORTRAN77 on a VAXCluster in 1986.
Still have my copy of "FORTRAN 77 For Engineers and Scientists" just in case.
It was very easy to pick up for someone who had only used AppleII or TRS-80 BASIC.

Don't know if it's still the case, but in FORTRAN IV you don't need spaces between keywords and variable names. So when the compiler sees "FORI=2" it has to look still further ahead to decide if this is a for-loop (FORI=2TO9DO) or an assignment to a variable named FORI. Decidedly not a context-free grammar; you can't even figure out the tokens without the ad-hoc parser getting involved.
